Archaeal diversity in deep-sea sediments estimated by means of different Terminal-Restriction Fragment Length Polymorphisms (T-RFLP) protocols [PDF]

, 2009
Despite the increasing recognition of the quantitative importance of Archaea in all marine systems, the protocols for a rapid estimate of Archaeal diversity patterns in deep-sea sediments have been only poorly tested yet.

An Explicit Test of Kill the Winner: Protistan Grazing and Phage Lysis Differentially Impact Fast‐Growing Bacterial Taxa in the Coastal Antarctic

Environmental Microbiology, Volume 28, Issue 2, February 2026.
We evaluated whether predators ‘kill the winner’ wherein protists and phages preferentially impact the most abundant members of bacterial assemblages over an austral summer with weekly dilution experiments. Seawater from 10 m was divided into two serial dilutions with either 0.2 μm (to evaluate protist grazing) or 30 kDa (to evaluate protist grazing ...

Phylogenetic shifts of bacterioplankton community composition along Pearl Estuary: the potential impact of hypoxia and nutrients

Frontiers in Microbiology, 2015
The significance of salinity in shaping bacterial communities dwelling in estuarine areas has been well documented. However, the influences of other environmental factors such as dissolved oxygen and nutrients in governing bacterioplankton communities ...

Microbial acetone oxidation in coastal seawater [PDF]

, 2014
Acetone is an important oxygenated volatile organic compound (OVOC) in the troposphere where it influences the oxidizing capacity of the atmosphere. However, the air-sea flux is not well quantified, in part due to a lack of knowledge regarding which ...

Colored Plastic Pollution Reshapes Aquatic Microbial Community and Resistance Profile via Divergent Pseudonatural Dissolved Organic Matter

Advanced Science, Volume 13, Issue 3, 14 January 2026.
By altering the quantity and chemical composition of polyethylene‐derived dissolved organic matter, plastic color dynamically regulates bacterial metabolic interactions, thereby reshaping community resistance expression and facilitating the dissemination of antibiotic resistance.

River bacterioplankton community responses to a high inflow event [PDF]

Aquatic Microbial Ecology, 2015
Microbes drive chemical cycling and productivity within river ecosystems, but their influence may shift when intense allochthonous inputs accompany high freshwater inflow (flood) events. Investigating how floods influence microbial processes is fundamentally important for our understanding of river ecology, but is generally overlooked.

Cyclonic cold-core eddy in the eastern North Atlantic. II. Nutients, phytoplankton and bacteriaplankton [PDF]

, 1987
A cyclonic cold-core eddy in the Northeast Atlantic of about 100 km in diameter at the sea surface was investigated in May 1985, approximately 3 wk after it had separated from the Polar Front.

Mechanisms of microbial carbon sequestration in the ocean – future research directions [PDF]

, 2014
This paper reviews progress on understanding biological carbon sequestration in the ocean with special reference to the microbial formation and transformation of recalcitrant dissolved organic carbon (RDOC), the microbial carbon pump (MCP).

Protistan Plankton Responses to Variable Light and Upwelling in the Peruvian Humboldt Current System: Insights Into Community Dynamics Under Environmental Change

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Our study reveals (based on experiments) the shifts in protistan plankton communities, serving as energy and organic matter source for higher trophic levels if the Humboldt Current System is affected by climate change as predicted by current models. This may have profound effects on fisheries in the Humboldt Current System.

Phytoplankton and bacterioplankton abundances and community dynamics in Lake Erhai

Water Science and Technology, 2013
The composition and seasonal variation of the phytoplankton and bacterioplankton community were investigated, and SPSS and redundancy analysis (RDA) were used to explore the relationship between the phytoplankton and bacterioplankton community dynamics in the typical plateau Lake of Lake Erhai from July 2009 to April 2010. Obvious seasonal variation of
